Recently I added new 4 nodes to existing oracle cluster which was running on Oracle 11g to be specific 220.127.116.11. adding nodes was success. but after that emctl is not running.
and the main issue is after few days getting error like ASM communication on new nodes. so I was increase the ASM memory and then it was ok.
but now the issue is I am getting the following error on new nodes only :
System state dump requested by (instance=3, osid=14808), summary=[system state dump request (kffIdentify1)]
and because of this database was slow, until I restart the database or server it was not fixed. can someone please help me in this.
